develop branch: text content leading space
pkra opened this issue · comments
I was working with the develop branch and ran into this rendering:
This came from \sigma(s) := \{ t \in S: s\cdot t \text{ is defined} \}.
with the latest release I get
I'm not able to reproduce that. Both branches produce identical results (your latter image) for me. Did you recompile the typescript after changing branches? (And rebuild the components, if you are using those?)

Yes, I did compile everything.

Let me know what you find out.
I use SRE to enrich things "manually".

Can you reproduce that by any chance?
OK, I can reproduce when the input is MathML rather than TeX. Looks like the <mtext> element is trimming the text incorrectly in the MathML input jax. During the enrichment, the MathML is serialized to send to SRE, and its result is parsed by the MathML input jax to turn it into the internal form again. That appears to be where the problem is occurring.
I'll check into it.
Are you working with TeX or MathML originally? The TeX \text{ is defined} should produce <mtext> is defined</mtext>, which is processed correctly through MathML input jax and SRE. But <mtext> is defined</mtext> does lose the initial space, as it is supposed to. Can you check if the MathML that you are enhancing has the U+00A0 rather than U+0020 as the first character. (You have given the enhanced MathML not the original MathML, and the space has already been moved by then).
I'm working with TeX originally. Here's what I get in between - seems like I'm missing   right away.

Hmmm. Here's what I get from the on-line web demos:
So something is funny there. Can you check that you also get the   in that demo?
Also, without the  , the output is correct, as the leading space should be trimmed in that case.
@dpvc I'm on node with the light adaptor.
OK, good point. Let me check that.
Something like
const TeX = require('../mathjax/v3/js/input/tex.js').TeX;
const HTMLDocument = require('../mathjax/v3/js/handlers/html/HTMLDocument.js')
.HTMLDocument;
const liteAdaptor = require('../mathjax/v3/js/adaptors/liteAdaptor.js')
.liteAdaptor;
const STATE = require('../mathjax/v3/js/core/MathItem.js').STATE;
const AllPackages = require('../mathjax/v3/js/input/tex/AllPackages.js')
.AllPackages.filter( x => x!=='bussproofs');
const tex = new TeX({ packages: AllPackages });
const html = new HTMLDocument('', liteAdaptor(), { InputJax: tex });
const MmlVisitor = require('../mathjax/v3/js/core/MmlTree/SerializedMmlVisitor.js')
.SerializedMmlVisitor;
const visitor = new MmlVisitor();
const toMathML = node => visitor.visitTree(node, html);
const tex2mml = (string, display) => {
return toMathML(
html.convert(string || '', { display: display, end: STATE.CONVERT })
);
};
Strange, all the component-based versions in the MathJax-demos-node repository produce the  , but not the direct version. Still looking to see what is behind that.
OK, it turns out that it is the new textmode extension, which is included automatically in AllPackages. It is not quoting the initial and trailing spaces properly.
One option would be to remove it from AllPackages as you do the bussproofs package. Another would be to patch textmacros on the fly, if you need that extension to be included. If so, let me know and I can work out the patch.
Ah! Thanks for tracking that down. I can disable the text extension (I wasn't using it).
I've made a PR that resolves the issue. Thanks for the report!
Fixed in v3.1 released today.
